Abstract

The present invention relates to a connector system for use in connecting conduits together, such as those used with an extracorporeal blood circulation system. The system has a male and female connector and a seal. The seal is operatively associated with the male and female connectors and forms a fluid tight connection between the male and female connectors. An inner surface of the seal and the inner surfaces of the first and second coupling ends form a continuous and smooth transitional surface.
